科罗拉多大峡谷的地质密码

<正>有山就有谷。世界上有很多大山大河,也就有很多大峡谷,比如中国的雅鲁藏布江大峡谷,巴西的Itaimbezinho大峡谷,尼泊尔的Kali Gandaki大峡谷,纳米比亚的鱼河大峡谷等,都是天下名胜。但说出不加前缀的大峡谷三个字时,人们会不由自主想到的那一个大峡谷——美国的科罗拉多大峡谷。在世界遗产委员会刚开始审定世界遗产名录的1979年,科罗拉多大峡谷即入选世界自然遗产。这绝非侥幸。科罗拉多大峡谷,其风华绝代,壮美雄奇,确实有其无可比拟的魅力,当得起地球上大峡谷的代表。     

Social mobility and reproduction among nineteenth-century Colorado silver prospectors

Popular cultural convention holds that, for those with enough gumption, the American frontier was a land of unparalleled opportunity. However, careful research throws doubt on the universality of this convention. Thus, the authors explore factors that increase or decrease opportunities for upward mobility in frontier towns. The authors' longitudinal study of late nineteenth century silver prospectors in Gothic, Colorado, demonstrates that while enthusiastic prospecting in Gothic did not lead to upward social mobility, it did provide enhanced reproductive opportunities.     

Internationalization: Institutions,People and Programmes in Colorado

This paper focuses on the internationalization of curricula, faculty and campus activities in a case study of colleges and universities in Colorado. ‘Internationalization’ is a recent trend in US higher education and is sometimes given as a reason for hiring foreign-born faculty. A survey was used to explore how the definition and degree of internationalization would vary by institutional mission, goals and size as well as by the interests and expertise of key administrators and staff. None of these factors accounted for the survey results. Instead, the results indicate inconsistencies in institutional definitions of internationalization and in the implementation of resulting programmes. These inconsistencies may be a reason why foreign-born faculty can receive a mixed reception and encounter varied support on US campuses and raise a number of issues for further research on the discourse of contemporary US higher education.     

LA-ICP-MS analysis of quartzite from the Upper Gunnison Basin,Colorado

We report the results of LA-ICP-MS analysis of 402 quartzite samples representing 48 collection loci in the Upper Gunnison Basin (UGB), Colorado and determine the extent to which the sources can be geochemically discriminated from one another using this non-destructive technique. The ability to differentiate among the sources would open the door to provenance studies of the quartzite chipped-stone tools and debitage that constitute 95% or more of most of the 3000-plus prehistoric site assemblages documented in the UGB. Our samples represent prehistorically quarried and non-quarried quartzite sources, including outcrop (primary) and gravel (secondary) deposits. The results reveal spatial and chronological trends in quartzite elemental composition that can be exploited for provenance determinations of quartzite artifacts from UGB sites, albeit using an assemblage-based sourcing strategy that differs from the familiar approach of “matching” obsidian artifacts to their statistically likeliest geological source. We offer a preliminary version of a sourcing protocol for UGB quartzite.     

Late Pleistocene protein residues from the Mahaffy cache,Colorado

This paper reports the analysis of protein residues from tools recovered in a cache within the city limits of Boulder, Colorado, USA. This cache included a total of 83 artifacts, all of which we subjected to cross-over immunoelectrophoresis (CIEP). Four of the 83 produced results, with residues from each of these reacting with antigens from a different taxon: one tool shows evidence of use on sheep, one on bear, one on horse, and one on camel. Varieties of sheep and bear have been present in Colorado throughout human history, but horses and camelids have been in the state either during the Pleistocene or the last 200 years. Several lines of evidence indicate that the cache cannot be recent, and our CIEP results therefore imply that the cache date to the late Pleistocene. Typological aspects of the artifacts in the cache are consistent with artifacts known to be Clovis, and the combination of CIEP and typological data thus indicate that the cache is Clovis as well. These data contribute to an increasing dataset documenting the broad range of animals other than elephants hunted by Clovis groups in North America.     

Immigrant "Illegality" as Neoliberal Governmentality in Leadville, Colorado

Abstract:  In this paper, I frame immigrant "illegality" as a local-scale technique of neoliberal governmentality. Drawing on recent work of anthropologists, I present illegality as a racialized, spatialized social condition which operates as governmentality by marginalizing and criminalizing immigrants, loosening the US border and forcing it into local spaces, and impacting immigrants' everyday lives and mobility. The paper then draws on a case study of Leadville, Colorado, to illustrate the utility of this framework. In Leadville, we see how through illegality neoliberalism seeps through scales. Illegality disciplines immigrant labor in service of the neoliberal order, turns all residents into surveillers of immigrants' subordinate sociospatial position, and masks contradictions within neoliberalism that arise particularly at the local scale. I argue that conceptualizing illegality as a governmentality technique provides a powerful tool for understanding changing state spatiality, especially ways in which neoliberalism is diffused and embedded into local economic, political, and social processes.     

Conspicuous Consumption and Outward Opulence as Seen in Two Victorian-Period Colorado Midden Assemblages

Archaeology as Built for the Tourists: The Anasazi Cliff Dwellings of Manitou Springs,Colorado

Anasazi-era archaeology sites have been extremely popular tourist attractions since the 1890s, but one site—the cliff dwellings in Manitou Springs, Colorado—stands apart because it is a fake. The site was constructed at the turn of the twentieth century as a more accessible tourist alternative to Four Corners-area Anasazi ruins. The story of its construction and how it continues to cater to its visitors offers insight into the ways in which archaeology sites function as tourist destination. The Manitou Cliff Dwellings forces scholars to consider questions of authenticity, authority, and how people engage the past.     

Working through theoretical tensions in contemporary archaeology: A practical attempt from southwestern Colorado

Archaeology should actively combine different paradigms to obtain a more complete understanding of the past. This paper argues for a practical combination of elements of the culture-historical, processual, and postprocessual approaches into a two-tier model. The first tierreconstructs the events of the past, using culture-historical and middle-range principles, and the secondconstructs a reflexive explanation of these events, which situates an analysis of the internal and external constraints on past human behavior within the specific theoretical and political positions of the analyst. The theoretical arguments are developed by means of an analysis of the prehistory of a segment of the mountains of southwestern Colorado.
